DUI lawyer costs in Arizona range from $2,500 to $25,000 or more depending on whether you face a standard misdemeanor under ARS 28-1381, an Extreme or Super Extreme charge under ARS 28-1382, or a felony Aggravated DUI under ARS 28-1383. Attorney fees reflect charge severity, court venue across Maricopa County, scope of litigation, and whether the case goes to trial.

Fee Ranges by DUI Charge Level in Arizona
Arizona separates DUI offenses into three statutory tiers, and attorney fees track closely to charge severity. Each tier involves different mandatory minimums, court procedures, and defense workloads that directly affect what you pay for representation.
Standard DUI under ARS 28-1381 covers driving while impaired to the slightest degree and the 0.08 BAC per se violation. First-offense misdemeanor cases in this category typically cost $2,500 to $7,500 in legal fees when resolved through negotiation or pretrial motions. These cases are heard in municipal courts throughout Maricopa County, including Tempe Municipal Court, Phoenix Municipal Court, Mesa Municipal Court, and Scottsdale City Court. Second-offense cases within 84 months carry steeper mandatory jail minimums and often require more extensive defense preparation, pushing fees toward the higher end of that range.
Extreme and Super Extreme DUI under ARS 28-1382 applies when a blood or breath test registers at 0.15 BAC or above (Extreme) or 0.20 BAC and above (Super Extreme). These charges carry significantly harsher mandatory jail sentences and higher fines than standard DUI. Defense often involves challenging chemical testing procedures, calibration records, and the admissibility of blood draw results. Attorney fees typically range from $5,000 to $15,000, reflecting the additional motion practice, potential expert consultation on blood testing protocols, and more complex negotiations with prosecutors. An experienced extreme DUI lawyer can identify suppression opportunities that directly affect case outcomes.
Aggravated DUI under ARS 28-1383 is charged as a class 4 or class 6 felony. This applies when someone is arrested for DUI while their license is suspended or revoked, commits a third DUI within 84 months, drives with a passenger under fifteen, or operates a vehicle while required to have an ignition interlock device. Felony cases proceed in Maricopa County Superior Court, involve grand jury or preliminary hearing proceedings, and require formal discovery management. Retainers for aggravated DUI defense typically start at $10,000 and can reach $25,000 or more when the case involves contested evidentiary hearings, expert testimony, or a jury trial.
| Charge Level | Statute | Typical Fee Range | Court Venue |
|---|---|---|---|
| Standard DUI (1st offense) | ARS 28-1381 | $2,500 – $7,500 | City/Municipal/Justice Court |
| Extreme / P13 | ARS 28-1382 | $5,000 – $15,000 | City/Municipal/Justice Court |
| Aggravated DUI (felony) | ARS 28-1383 | $10,000 – $25,000+ | Maricopa County Superior Court |
| Any DUI proceeding to jury trial | Varies | +$3,000 – $10,000 | Varies by charge level |
Flat Fee vs. Hourly Billing and What Each Includes
Most Arizona DUI attorneys use one of two billing structures, and understanding the difference prevents surprises. A flat fee means you pay a single, agreed-upon amount for a defined scope of work. An hourly rate means the final bill depends on how many hours your case consumes. Some firms use hybrid arrangements that combine both approaches.
Flat fee arrangements are the standard for misdemeanor DUI defense in Arizona. A typical flat fee for a standard ARS 28-1381 case covers arraignment, review of police reports and body camera footage, pretrial conferences, standard motion practice, and negotiation with the prosecutor. Before signing a retainer, ask specifically whether the flat fee includes representation at the ADOT Executive Hearing Office for your MVD implied-consent hearing under ARS 28-1321, or whether that is billed separately. Many firms also exclude jury trial preparation and trial days from the base flat fee, quoting an additional amount if the case cannot be resolved short of trial.
Hourly billing is more common in felony Aggravated DUI cases under ARS 28-1383, where the scope of litigation is harder to predict at the outset. Hourly rates for experienced DUI defense attorneys in Maricopa County generally range from $250 to $450 per hour. The advantage is that you pay only for actual time spent, but the disadvantage is unpredictability. If your case involves extensive suppression litigation based on decisions like State v. Butler, 232 Ariz. 84 (2013), or State v. Valenzuela, 239 Ariz. 299 (2016), attorney hours can accumulate quickly during briefing, officer subpoenas, and evidentiary hearings.
What to clarify before you sign: Does the fee include MVD hearing representation? How many court appearances are covered? Is motion practice (suppression motions, motions to compel disclosure) included or extra? What happens if the case goes to trial? Are expert fees and independent lab testing costs separate? A written retainer agreement that answers these questions protects both you and your attorney from misunderstandings.
Hidden Costs Beyond Attorney Fees
Attorney fees represent only one piece of the total financial impact of an Arizona DUI arrest. Several mandatory expenses apply regardless of whether you hire a lawyer, and understanding them helps you budget realistically and evaluate why investing in effective defense can reduce overall costs.
Fines and surcharges for a first-offense misdemeanor DUI under ARS 28-1381 can exceed $2,500 after mandatory assessments are added. Extreme DUI penalties under ARS 28-1382 carry substantially higher base fines. Aggravated DUI felony convictions under ARS 28-1383 include prison assessment fees, felony surcharges, and potential restitution in crash-related cases.
Ignition interlock devices are required upon conviction for most Arizona DUI offenses. Installation runs approximately $75 to $150, with monthly calibration and monitoring fees of $60 to $100. The mandatory interlock period ranges from 6 months for some first offenses to 18 months or longer for Extreme DUI and repeat offenses. Over a 12-month period, total interlock costs often exceed $1,500.
Insurance rate increases follow a DUI conviction and typically persist for three to five years. Arizona drivers with a DUI on their record can expect annual premium increases of $1,000 to $2,000 or more, depending on their insurer and driving history. Some carriers drop coverage entirely, forcing you into high-risk pools with elevated rates. Over three years, insurance increases alone can cost more than the attorney fee.
Alcohol screening, education, and treatment programs are mandatory after any Arizona DUI conviction. Screening costs typically range from $100 to $300, while the required education or treatment program can cost $500 to $1,500 depending on the assessed level of intervention. More serious offenses or repeat convictions may require intensive outpatient treatment programs with higher costs and longer time commitments.
License reinstatement and MVD fees include the ADOT reinstatement fee and any associated costs for compliance verification. If your license was suspended through the implied-consent process under ARS 28-1321 and you missed the 15-day hearing request window, you face additional months of suspension and corresponding reinstatement hurdles.

How to Evaluate Value When Comparing DUI Lawyers
Compare Scope, Not Just Price
A $3,000 flat fee that excludes MVD hearings, motion practice, and trial preparation may cost more in the long run than a $6,000 retainer that covers the full case lifecycle. Request a written breakdown of what each quoted fee includes for your specific ARS 28-1381, 28-1382, or 28-1383 charge.
Ask About Courtroom Experience in Your Venue
DUI defense outcomes are shaped by the specific court where your case is assigned. An attorney who regularly appears in Tempe Municipal Court, Phoenix Municipal Court, or Maricopa County Superior Court understands local procedures, judicial preferences, and prosecutor tendencies that affect strategy and timing.
Verify Background in Both Prosecution and Defense
Attorneys with experience on both sides of DUI cases understand how the prosecution builds its case and where vulnerabilities exist. Former prosecutors and judges bring perspective on charging decisions, plea negotiations, and evidentiary standards that defense-only attorneys may lack.
Evaluate Expertise with Chemical Testing Challenges
Arizona DUI cases increasingly turn on the admissibility of blood and breath test results. After State v. Butler and State v. Valenzuela, consent and search issues around blood draws are regularly litigated. Ask whether your attorney handles suppression motions, retains independent toxicology experts, and orders independent blood retesting when appropriate.
Why Clients Choose Oliverson Law
Frequently Asked Questions
A first-offense misdemeanor DUI under ARS 28-1381 typically costs between $2,500 and $7,500 in attorney fees when resolved through negotiation or pretrial motions. That range assumes the case does not proceed to a jury trial. If trial preparation, expert witnesses, or contested suppression hearings become necessary, fees can increase. Separate charges may apply for MVD implied-consent hearing representation and independent blood retesting through a private laboratory.
Higher fees often reflect broader scope of representation rather than a guarantee of results. Attorneys who include motion practice, MVD hearings, expert consultation, and trial preparation in their retainer provide more comprehensive defense coverage. In courts like Phoenix Municipal Court or Maricopa County Superior Court, experience with local procedures, judges, and prosecutors can directly affect case strategy. Compare what each fee includes rather than focusing on the dollar amount alone.
Beyond attorney fees, expect court fines and surcharges that can exceed $2,500 for a first offense under ARS 28-1381. Add mandatory alcohol screening and treatment classes, ignition interlock device installation and monthly monitoring fees, license reinstatement charges through ADOT, and significantly increased auto insurance premiums lasting three or more years. Independent blood retesting or toxicology expert fees may also apply if your defense requires challenging the chemical test results.
Flat fees provide cost predictability and are common for misdemeanor DUI cases handled through pretrial resolution. Confirm whether the flat fee covers MVD hearings, suppression motions, and trial days or stops at a plea offer. Hourly billing is more common in felony Aggravated DUI cases under ARS 28-1383 where litigation scope is uncertain. Some firms use hybrid models with a flat retainer plus hourly billing beyond a defined scope. Always get the fee structure in a written retainer agreement.
Misdemeanor DUIs file into the municipal court where the arrest occurred, such as Tempe Municipal Court, Phoenix Municipal Court, or Scottsdale City Court, or into a Maricopa County Justice Court. Each court has different calendars, pretrial procedures, and judicial expectations for motion practice. Felony Aggravated DUI charges under ARS 28-1383 go to Maricopa County Superior Court, which involves grand jury proceedings, formal discovery, and longer timelines that increase attorney hours and fees.
